bit of a long read "It is most likely going to get colder not warmer" breakingviewsnz.blogspot.com/2024/10/ian-bradford-it-is-most-likely-going-to.html?m=1closing paragraphs Significant linear relations are found between the average air temperature in a solar cycle and the length of the previous solar cycle, for 12 out of the 13 meteorological stations in Norway and in the North Atlantic. A significant trend is found between the length of a cycle and the temperature in the next cycle. This enables predictions to be made about the temperature in the next cycle. A longer cycle predicts lower temperatures during the next cycle. Richards et al analyzed the length of cycles from 1610 to 2000. They found a correspondence between long cycles and a minimum number of sunspots. Their study suggests that the length of sunspot cycles should increase gradually over the next 75 years, accompanied by a gradual decrease in the number of sunspots. This of course, means a gradual cooling of the Earth.
The sun goes through warming and cooling cycles every 11 years. The cycles are tracked by the number of sunspots on the surface. Record keeping began in 1755 with cycle number 1. Solar cycle 25 began in December 2019. Half way through the 11 year cycle the Sun’s activity becomes very intense and stormy, leading to its peak or solar maximum. At the solar maximum the Sun’s north and south magnetic poles swop places and the Sun’s activity begins to quieten down, until it reaches a solar minimum.
Sunspots are dark areas on the Sun’s surface. Intense magnetic fields push up from within the Sun’s interior. These areas are dark because they are cooler than the rest of the sun. The largest sunspot groups can cover large swaths of the Sun’s surface and be many times the size of the Earth. The number of sunspots is a measure of the Sun’s activity.
In 2019, 218 days went by without sunspots, the highest number of spotless days since 1913. At the end of December 2019 two reversed polarity sunspots appeared. These indicated that Solar cycle 25 had started. The maximum of this cycle is predicted to peak from mid 2024 through to mid 2025. Cycle 25 will end around 2030.
Below is a graph of solar activity from 1980-cycle 21 to a predicted cycle 26 mid-way between 2030 and 2040. The key point here is that solar activity is constantly falling off. Why is this significant? If there are fewer solar storms, the Earth’s climate gets colder. This is exactly what happened between 1645 and 1715 when the normal 11 year sunspot cycle vanished. This period called the Maunder Minimum was accompanied by bitterly cold winters in the American colonies. Fishing settlements in Iceland and Greenland were abandoned. Icebergs were seen near the English Channel. The canals of Venice froze. It was a time of great hardship.
There are a number of researchers who predict a cold spell which they are calling a Mini Ice Age. It would last for a few decades. Professor Zharkova claims it has already started. We shall just have to wait and see.

Was just listening to an interview on RNZ with the head of Datacom in NZ.
I am clearly very ignorant of all things datacentre.
So, a standard google search uses enough power to run a lightbulb for 11 seconds. An AI question uses enough power to run a lightbulb for 3 hours. So AI is going to dramatically increase the amount of power consumed in IT / data centres. Disappointingly, they did not say if a standard lightbulb is still a 100watt incandescent, or a 1 watt LED, as an engineer I find their lack of units offensive.
They measure data centres in Megawatts. A small one is 10-15 megawatts.
The new big ones are like 100 megawatts. It wont be long until data centres in NZ are using the same amount of power as the Tiwai Pt Aluminum smelter.
Anyway, his main point was that solar is about as useful as tits on a bull for data centres, because they need a continuous and reliable power supply. Same with wind generation - intermittent can't be used for data centres. Whowaddathunk?
They like geothermal and hydro, cause it is reliable, and 'renewable'. All the big global data companies are buying certificates that say their power / product is 100% renewable. As in Amazon, Microsoft etc. This is a big deal for them, cause, for example, all of the Aussie data centres are 100% coal fired...
I find it perverse that the latest advances in technology are actually taking us backwards in what we are being told is the most pressing problem facing human civilisation, as in AI, ChaptGPT and all the silly little pop ups in the latest IT browsers are going to lead to the end of civilisation due to increase coal consumption. Or at least that is the narrative.

Thinking about vulnerability , a drone and a someone with a grudge about something could really cause some grief at a data centre .

You’d hope that the silverdale mobs will be installing electronic signal jamming gear . Reminds me of a story when I was starting out as a designer for a very large infrastructure company in London. 300 engineers / designers on one floor, we were under very strict instructions to save all work to the server. Under no circumstances were project files to be kept on your local drives, for security of course. One night the IT service provider, Acensure, completely fucked up a back-up and lost ALL of the meta data for, well, everything. So, the project files still existed, but without the meta data you simply can't find them. So, we lost at least the last 3 months of design work, and in some instances the last 6 months of design work. This was for a hundreds of millions of pounds infrastructure programme. 300 staff suddenly sitting with nothing to do. Unless you broke all the rules and had project files on your C drive. So what to do? admit you broke the rules and specific instructions, and save the company months of work by continuing with your project, or go to the pub with everyone else? |

Yet another "Inconvenient truth" the Climate Catastrophists want to keep hidden breakingviewsnz.blogspot.com/2024/10/eric-hussey-carbon-alarmists-are-silent.html?m=1closes So, for at least two years, we were forced into a natural experiment involving reduced production – on the part of the general populace – of carbon dioxide, the main culprit in global warming.
As I say this last part, let me own up to not having looked at all the data – as if I could trust it. This is a commentary on the popular media as much as anything. With that caveat, let me ask, why are we not hearing about a beautiful natural experiment from two years of lockdown?
If carbon dioxide production by evil humans is the culprit, we should be hearing about new data showing 1) reduced CO2 during lockdown and 2) a flattening or direction change of “climate change” temperature curves. Given proper attention to time lags, we should be hearing “See, I told you so,” should we not? Instead, on this narrow subject, it seems to be radio silence. If we’re not hearing about a grand glorious result of a fortuitous natural experiment, why are we not hearing about a grand glorious result of this fortuitous natural experiment? Should we not be hearing about a natural verification of the climate change belief system? If not, why not?
Could it be that shutting down the economies of the Western world, killing small businesses, and thereby (accidentally?) reducing the “carbon footprint” of the world…made no difference?
The facts are over this period the oceans continued releasing entrained CO2 at the same steady rate of release that has been observed over several hundred years.

So AT, Auckland Transport, are proudly promoting their wonderfullness at buying battery ferries.
But things aren't as flash as they would like you to believe.
So apart from paying moonbeams for smaller carbon ferries then the large alloy ones. It sounds like these 4 are funded.
They go to commission 4 more smaller (27m) ones....Opps,no coin cancel them.
But now they have run into a wee issue the little birdy is telling me.
That issue being finding coin to launch the boats and then another 20 million to install charging at 4 places so they can charge the bloody things.
As someone in there was smart,or possibly the total opposite of that, they call to fit Jet units, the ones that take twice the grunt propellers do. So not only have they no fast charging and once they do charge one it can doc 1 maybe 2 trips before needing rechargings, but if they were shafts to props that 1-2 becomes 3-4.
The specifications work must have been done by the same mob who reckons we need to spend more than the cost of a new large cruise ship, with all the very upmarket restaurants, theatres, staterooms and etc they contain, to by a Cook St ferry that has a cafe and some train tracks.
I reckon what NZ needs is a bunch of people who know good shit, know their limitations, aren't 5yo's with 50 years experience and the public are OK with to get together and make sound wise decisions for the country as a whole. Maybe we could call it a Government.

Maybe we could call it a Government. Interesting reading, seems a bit incestuous when reading the CEO Michael Eaglen of "EV Maritime" evmaritime.com/ , the "designers" is the ex CEO of Mc Mullen and Wing who just happen to be building these cats. Eaglen does have a Naval Architecture qualification and worked for Alan Warwick for a time (and is mates with Mr and Mrs Bad Kitty) so you would think he would know better. In particular, as you say, you do not even think about jets unless you want to cruise at 30kts + or are working in shallow waters/areas with lots of obstructions. Makes no sense in this case.
Edit - talked to someone whose opinion I trust who knows Eaglen, says he is a very smart dude so will be interesting to see how all this pans out. The Porters (McM and W) are the backers of EV Maritime

Michael Eaglen is EV Maritime. Richard Edlin is Cove Boatworks and BK's mate.....and a bloody good boat builder and a rural dweller, Matakohe just down the road from us. But incestuous is a word I'll not take out  Some are fitting jets and outboards as they can get a 5 year survey where shafts are 3 + 2. No idea if that was an input to the battery ferries and judging by the obvious lack of for thought in places around and on them I can't see it being likely. There's a lot more but with NZ being so small things can be tracked back and people get in the shit,usually wrongly but as they are rarely top of the food chain there is a risk they will be thrown under the dingy of things go too public. So I don't post a lot I could. When it comes to building battery boats EV Maritime is about to be eclipsed big time. I think EV are trying to be a 'technology' company i.e. sell sussed ideas and things EV more than build actual boats. But WTF is AT spending coin on carbon boats when alloy works and the city is more than broke. The money that's probably costing could have brought a couple of the smaller options they had to dump. |

I am not confusing the two names, Eaglen and Mrs BK worked together at High Mod/SP in the past (check his profile at Linked In) and I too know Richard and that he was the builder of BK (well all but the hulls).
Agree that EVM look to be a technology co, milking a potential market for which there is a current demand, even if perhaps rather uninformed clients.

Oh yeah, Mrs BK works with many and is quite a player in the game, she goes by the moniker 'Clever Fox' is her. She does and check engineering and shit like stability.Very highly regarded in the field of composite engineering, she is a very smart cookie. Also handy when you want crew for crashing a helicopter into the harbour just off North Head  But then as has been mentioned in more than a few YC bars, where does Mr BK fit in if she is so smart Me shit stir the big fella? Never |
